I built a free app that turns your audio into backing tracks—here’s the before and after

I'm the developer of Soniqo Music. I built it to turn an audio file you already have into a backing track you can keep on your phone. The demo compares the original with the instrumental, then shows a key change. It's Android footage; the app is also available on iPhone and iPad. The words on the video were added in the edit—the app doesn't show synchronized lyrics. Demo: Watch the original/instrumental and key-change comparison Import WAV, M4A or MP3, separate the vocals and instruments, and export a WAV. You can also isolate bass or drums, change the key, or slow down and repeat a section for practice. All current tools and WAV exports are free. No account, ads or subscription. After a one-time model download, processing runs on the device. Keep the app open while it works; some vocals or instruments can leak between parts. iPhone and iPad (iOS/iPadOS 18+): App Store Android (10+, supported 64-bit devices): Google Play What do you currently use to make backing tracks? Music: Jingle Bells by Sascha Ende (2013), CC BY 4.0. Excerpted, vocals separated and key adjusted in Soniqo Music. Original recording   submitted by   /u/ivan_digital [link]   [comments]
